Error messages according to the spec

[christopherL91]

Awesome lib! I'm really impressed on the quality of the lib. According to the spec there's a number of standardized error messages that are recommended to return if an error occurred, would this be something we could add to this lib?

Why is the soap module not included in the lib? Are there any particular reasons for not doing this?

Thanks!

The error messages is definitely something that could be added to the library, since the library throws it's own type of error this could probably be added to the error without much trouble.

As for having the soap library as a peer dependency, i thought that if someone uses the soap library for other things they can decide themselves what version of the library that they want as long as it's within the supported version-range.
